The move will see the Australian-born Princess cut down on her royal duties as she spends much of her time with the children in Geneva.

The move was confirmed by Danish royal head of communications Lene Balleby, with further information released in a statement, posted to Facebook.

"At the beginning of the new year, Prince Christian, Princess Isabella, Prince Vincent and Princess Josephine will begin a 12-week school stay at the International School of lemania-Bees in Switzerland," the statement in Danish revealed.

"With the school stay, the Crown Prince party wants to give their children the opportunity for a common experience in an international environment."
